LOUIS ROTH, OF NEW YORK, Y., ASSIGNOR TO STERLING BRONZE COMPANY, OF NEWYORK, N. Y., A CORPORATION OF NEW YORK.

ELECTROLIER.

Application filed June 27,

To all whom it may concern:

Be it known that I, LOUIS ROTH, of the city of New York, county ofBronx, and State of New York, have invented a certain new and usefulElectrolier, of which the following is a specification.

This invention is an electrolier wherein provision is made for hanging aglobe or dome directly from a canopy in such manner that said globe ordome may be easily attached, detached, and raised or lowered asrequired. Furthermore, provision is made for raising or lowering anelectric lamp as may be required with reference to the position of theglobe or dome, said means operating to securely retain the electrio lampin a suspended relation to the globe or dome so as to be free fromcontact therewith, whereby electric lamps of difl'er ent sizes may beused in connection with globes or domes varying in shape and size.

One part of the invention consists of a canopy provided with a pluralityof apertures in the form of keyhole slots, combined with a globe, ondome, and a plurality of suspenders, the latter being preferably in theform offlexible chains the links of which are rounded, although otherforms of suspenders may be utilized. The links of the suspenders passthrough the slots in the canopy and when the weight of the globe isimposed upon the suspenders the links are drawn into the reduced ends ofthe key-hole slots, thus locking the suspenders to the canopy, althoughit is apparent that the links may be pulled by hand outof the reducedends of the slots and then the links can be drawn freely through theenlarged ends of the slots so as to raise or lower the suspenders andthe globe or to detach the suspenders from, or attach them to, thecanopy.

The invention consists, further, in the combination with a bowl or globeprovided with apertures adjacent its upper margin, of a plurality ofhangers fitted in said apertures, each hanger being provided with aslotted arm extending inwardly of the globe or dome, and suspendersconnected to said slotted arms extending inwardly of the globe or dome,and suspenders connected to said slotted arms of the hangers, wherebythe suspenders and the hangers cooperate jointly Specification ofLetters Patent.

through Patented June 22, 1920. 1919., Serial No. 307,074.

for connecting the suspenders detachably and adjustably to the globe orbowl.

A further part of the invention consists in providing the canopy with asleeve which is adapted topass certain conductors for feeding electriccurrent to an lncandescent lamp, said sleeve having a tapering internalthread, combined with a split threaded bushing screwed into the sleeveand cooperating with the conductors for frictionally gripping the sameto or releasing the same from the bushing, whereby said bushing may betightened or slackened for the purpose of retaining the conductors infixed relation ting the conductors to slide through said canopy to theend that the lamp be raised or lowered within the globe as required.

Other features and advantages of the in Vention will appear from thefollowing description taken in connection with the drawings, wherein-Figure 1 is anelevation with parts in section of an electrolierembodying this invention. Fig. 2 is a horizontal section taken in theplane of the dotted line 2-2 'of Fig. 1 looking upwardly, the partsbeing shown on an enlarged scale. Y

Fig. 3 isa detail perspective view of one of the hangers.

A designates the canopy, B a globe or bowl, and C are the suspendersattached to the canopy and the bowl or globe whereby the weight of saidglobe is suspended directly from the canopy.

The canopy is a metal fitting, composed of a cast piece, or a metalspinning or stamping, the mode of producing said canopy not beingmaterial. As shown, the canopy is hollow in construction to produce atop flange a and a pendent central member a,'the latter being formed atthe center with a sleeve b. The canopy partially houses or incases thejunction box D, and means suitable for the purpose are provided forfixedly attaching the canopy in position, the means shown being thescrews 0.

According to this invention, the canopy is provided with a plurality ofslots E, a suitable number being formed in the central pendent member a,three being shown in Fig. 2. Each slot consists of an eye e and to thecanopy or of permitthe dome has a tendency to draw penders into thenarrow parts of the slots,

an elongated part e, the slot being of the :kind termed a key-hole slot.The slots are spaced equi-distantly in the canopy,

and they open through the underside of said canopy so as to be easilyaccessible.-

The suspenders C may be composed of rods, chains, cables, or otherwise,but itis preferred to use chains the links of which are globular in formand are flexibly connected. The links are adapted to pass through theeyes 6 of the key-hole slots in the canopy, and after sliding therein tothe required positions said. links are shifted into the narrow parts 6of said slots, as a result of which the flexible chain suspenders arelocked to the canopy. The slots are so positioned in the canopy that thepull of the flexible suspenders and the weight of the susand thusprovision 1s made for arresting the chains from accidentally slipping inthe slots so as to become detached from the canopy except by manualmanipulation.

The globe or dome B is of any desired shape and dimensions, it beingpreferred to use a '-dome of transparent or translucent material such asglass. Said dome is shown as closed on the bottom and open at the top,the dome being provided with a plurality of apertures 7" near the uppermargin thereof. Said apertures accommodate the hangers F, one of whichis shown detached in Fig. 3 and two are fitted to the globe, see Fig. 1.Each hanger is composed of a piece of metal bent at two .pointsintermediate its ends to produce an angular part f and an arm f, one endportion of the hanger being provided with a head 9 and the arm f havinga slot 715 enlarged at the end 'to form an eye it, said slot 72, itbeing of key-hole formation. The angular part I of the hanger. is passedthrough an apertare f of the dome so that the head 9 lies, in snugrelation to or in contact with the" globe on the outside thereof,whereas the .arm f of said hanger extends inwardly of the globe,

at an angle to the inner face thereof,see Fig. 1. he hanger is thusfitted detachably to the apertured globe sov that the slotted armisconveniently positioned for 'the attachment of the flexible Suspender;

hanger may be and prefpresent a neat appearance.

One of the lower links of the flexible suspender passes through the eyeh of the hanger and is drawn to the requiredlength, after which the linkof said suspender is slipped into the reduced-part or slot It, thusproviding a detachable and adjustable'con-f nection between thesuspender and the globe, said slot occupying such a position in thehanger that the weight of the globe draws the flexible Suspender intothe slot is. connected in the usual manner.

'is in concentric relation order to raise .or lower the lamp within ofthe, globe.

suspenders attached to globe, the :upper portions of said suspenders.

in order to retain the suspender againstaccidental separation.

Through the sleeve 2) of the canopy passes the conductors G which carrya lamp socket i, to which an incandescent lamp I Said sleeve .7) isprovided with a tapering opening in which'is tapped a female thread, producing a tapering threaded opening.

male threaded bushing J is screwed into this threaded sleeve,.saidbushing being split as 1 and 2 and the lower part of the bushing beingprovided with a knob or knurledoperating piece j. The bushing to thecanopy and the sleeve '1) thereof, thus permitting the conductors G topass through said bushing. When turned in one direction, the bushingshown in Figs.

is closed by the tapering thread in the sleeve and itithus acts to gripthe conductors Gr for suspending the lamp in a desired relation to thedome, but by rotating the bushing in the opposite-direction, conductors,thus permitting said conductors to slide through the bushing and sleeve1iln t e dome, whereby lamps of different sizes may be attached tothesocket and adjusted to occupy a desired relation to the globe,without being in actual contact therewith.

From the foregoing description it will-be seen that the globe-may beraised or lowered as required with reference tothe canopy, that one or.more suspenders can easily be detached so as to swing the globe asideon one or two suspenders, that the globe may be mounted or dismountedeasily and quickly, and that the lamp can be raised or lowered withoutdisturbing the position The devices are simple, efficient, reliable andeconomical of manufacture.

Having thus fully what I claim as new, Letters Patent :is:-

1. An electrolier embodying a ceiling canopy positioned forsubstantially incasing a ceiling junction box, said canopy beingprovided with a plurality of key-hole slots, a globe, and a plurality offlexible said globe, said flexible suspenders being'adjustably anddetachably connected with the slotted portion of said ceiling canopy.
